Draining Fresh Water
Opening manual safety valve/drain valve
1. Switch off the water pump.
2. Open all water taps, showers, etc.
3. Open the safety/drain valve by lifting the
tab (This is yellow in colour).
4. The system will drain directly below the
vehicle through the clear plastic hose on
the safety/drain valve. Check that all water
has emptied out (7–10 litres). Leave the
valve in the open position until the next
time the hot water cylinder is used.
5. Check that the breather valve is allowing
air to enter the hot water cylinder, when it
is being drained, and that the clear plastic
hose is not obstructed.
Heat Transfer Fluid
The central heating system must be is filled with
Heat Transfer Fluid (HTF); a solution of 50%
ethylene glycol antifreeze and 50% water.
The antifreeze manufacturer will have a
maximum water hardness recommendation,
though deionised water (0 ppm) is always
preferred. Read the product label or contact
the product manufacturer for details.
Alde recommends Alde Premium G13 Ready to
Use Antifreeze.
50:50 ethylene glycol antifreeze and water
will protect against frost down to -35–-37 °C.
A refractometer and/or hydrometer can be
used to measure the strength of the antifreeze
solution.
Corrosion protection will vary depending on
the lifespan of the antifreeze. Read the product
label or contact the product manufacturer for
details.
WARNING: Always replace the HTF in
accordance with the antifreeze
product’s lifespan. If in any doubt,
replace the HTF after 2 years.
WARNING: The boiler must NOT be
switched on if there is no HTF in the
system.
The corrosion inhibitors found in ethylene glycol
antifreeze may not be cross-compatible. When
topping up or replacing the HTF, ensure the
new antifreeze is compatible with the current
antifreeze product. Read the product label or
contact the product manufacturer for details.
NOTE: As a guideline, blue and red
antifreeze products are NOT
compatible with each other, but VAG
G12++ and G13 spec antifreeze
(magenta) is compatible with both.
Failure to fill with suitable HTF may result in
severe damage to your Alde system, and is not
covered under warranty. We recommend you
contact the Bailey retailer for the replacement
of HTF.
